Rubidium-Xenon Gaseous Gyroscope by Lisa Lust & Dan Younger
Micro-electromechanical gyroscopes are widely used to in devices as diverse as game controllers and weapons guidance systems. They work by vibrating a tiny mass and then measuring how it is pushed around by Coriolis forces during rotation. But they have a number of drawbacks; say Lisa Lust and Dan Youngner from the aerospace equipment company Honeywell International in Morristown, New Jersey, US.
Lust and Youngner have come up with a new type of gyroscope that avoids these problems. It is essentially a cavity containing a mixture of rubidium and xenon atoms that can be controlled using two lasers. They say the device is low powered, physically small and robust since it has no moving or vibrating parts. They suggest it could be used to help uncrewed vehicles and robots navigate. Or it could aid personal navigational when GPS is not available – for example, inside a cave or large building.
